Для заданного в таблице режима нагрузки исполнительного механизма построить нагрузочную диаграмму Мс = f(t), определить режим работы, рассчитать мощность и выбрать тип асинхронного двигателя с короткозамкнутым ротором с количеством пар полюсов р, для длительного, повторно-кратковременного и кратковременного режимов работы провести проверку двигателя на перегрузочную способность, расшифровать обозначение типа двигателя, рассчитать и выбрать плавкую вставку предохранителя или тепловой расцепитель автомата, начертить схему магнитного пускателя: 1 нереверсивного, 2 реверсивного и объяснить принцип работы реверсивного МП.
